DVD+R DVD-R

[Chriss]

Hey!

So, I've got a laptop, with a DVD rewritter. I bought some DVD+R DVDs, and put them in. Laptop asks for DVD-R DVDs.

Is this a hardware, or software thing?

(Sorry, I don't really understand the problem, which makes asking the right question difficult)

As far as i understand it, - and + variation of rewriteable dvd's was a mini format war that neither really won. Much like HD DVD and blue ray

I suppose seeing as it was quite cheap to have dvd writers to be able to write both, most do. The differences between the 2 formats i do not know. It is however a hardware dependant issue so seeing as your writer asks for dvd-r then that's what you must give it.

You will find a better answer from google

How old is the laptop?

I'd be really surprised if it's a recent laptop and doesn't support both formats.

My computer is 9 years old, so relatively, it's new. It's a few years old, just before the new fangled dual core etc came out.

Is it worth playing about with other software to try and make it record onto DVD+?

you could find out what model the DVD drive is and then upgrade the firmware on it to make it recognise more range of media.

Most manufacturers played safe at the end and supported both formats of both DVD+R and DVD-R, but then we had Blu-ray and HD DVD format wars, but what started it off in the beginning was VHS (reasonably good quality but cheaper to manufacture)and Betamax (better picture quality but not so popular due to higher production costs raising the price in the end).

This folowing article in Wikipedia;

The DVD+R format is divergent from the DVD-R format. Hybrid drives that can handle both, often labeled "DVD±RW", are very popular since there is not a single standard for recordable DVDs. There are a number of significant technical differences between the "dash" (it's not a minus symbol) and the "plus" format, although most users would not notice the difference. One example is the DVD+R style ADIP (ADdress In Pregroove) system of tracking and speed control being less susceptible to interference and error which makes the ADIP system more accurate at higher speeds than the LPP (Land Pre Pit) system used by DVD-R. In addition, DVD+R(W) has a more robust error management system than DVD-R(W), allowing for more accurate burning to media independent of the quality of the media. Additional session linking methods are more accurate with DVD+R(W) versus DVD-R(W), resulting in fewer damaged or unusable discs due to buffer under-run and multi-session disks with fewer PI/PO errors.[3]

Like other "plus" media, it is possible to change the book type to increase the compatibility of DVD+R media. This is also known as bitsetting.[4]

As of 2007, the market for recordable DVD technology shows little sign of settling down in favor of either the "dash" or "plus" formats, which is mostly the result of the increasing numbers of dual-format devices that can record to both formats; it has become very difficult to find new devices that can only record to one of the formats. However, because the DVD-R format has been in use since 1997, it has had a five-year lead on DVD+R. As such, older or cheaper DVD players (up to 2004 vintage) are more likely to favor the DVD-R standard exclusively[5], and when creating DVDs for distribution (where the playing unit is unknown or older) the DVD-R format would normally be preferable
